Shorten Says There Will Always Be Suspicions Of Guns For Votes

Meantime, the Nats are grouping to get the Adler gun ban relaxed.

Opposition Leader Bill Shorten says the National Party "sense blood in the water."

CANBERRA – Opposition Leader Bill Shorten has dismissed criticism that he is politicising the 1996 Port Arthur massacre and declared there will "always be suspicions" the Prime Minister is prepared to water down gun laws in return for votes.

The Liberal Democrat has accused the Turnbull Government of deceiving and "dudding" him on a deal to vote in the Senate for the Government's industrial relations laws, which have just passed the House.

A temporary ban was placed on the seven-shot, lever-action shotgun in 2015

A magazine can be emptied in a matter of seconds

It can fire seven rounds with capacity for an eighth

Proponents want it help deal with feral animals

Opponents say it is too powerful and could end up in the wrong hands

The future of the seven-shot lever-action Adler shotgun is separate to the national firearms agreement struck by them Prime Minister John Howard in the wake of the 1996 Port Arthur massacre.

Separately, after Lindt café siege in Sydney, the Federal Government wanted a review of the Adler's classification and imposed a temporary ban while states and territory justice ministers reviewed the weapon.

In Australia, guns are classed as A, B, C or D depending on their capability. A is relatively easy to get, while C or D are highly difficult. There is no current consensus on the seven shot Adler, but a five shot, leaver-action Adler is available.

"The ban will remain in place until such time as the state and territory governments conclude the review because they are responsible for the regulation of firearms," Foreign Minister Julie Bishop told reporters in Canberra.
